History and Engineering

Planning and Construction

The Idamalayar Dam project began as part of Kerala’s broader initiative to harness its rivers for energy and agriculture. Envisioned in the late 1960s, the dam was constructed to tap into the region’s high rainfall—averaging 6,000 mm annually—by capturing the runoff from a 381 km² catchment in the Western Ghats (Alchetron). Construction commenced in 1970, but the challenging terrain, labor unrest, and technical hurdles delayed completion until 1987, considerably increasing project costs (Alchetron).

Structural Details

Type: Concrete gravity dam
Height: 102.8 meters
Length: 373 meters
Reservoir Capacity: 1,089 million cubic meters (gross)
Hydroelectric Generation: 75 MW (two units of 37.5 MW each)
Annual Output: Approx. 380 GWh
Spillway: Ogee-type with four radial gates, handling up to 3,012.8 m³/s (OneIndia, Wikipedia)

The dam’s tail-race water is diverted for irrigation, benefitting over 14,000 hectares via the Bhoothathankettu Barrage.
